Pivot Beverage Cap Venting With Integrated Waterproof Gasket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beverage container caps with pivot valves and waterproof gaskets require additional, smaller waterproof gaskets for vent holes, increasing production and installation costs and posing a choking risk due to their small size and ease of detachment.
Innovation Solution
A cap design where a waterproof gasket with a liquid through hole and at least one vent is formed integrally, eliminating the need for a separate waterproof gasket for the vent hole, and featuring a pivot valve with a hemispherical pivot part and nozzle part that switches between closed and open states to control fluid flow and venting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate waterproof gasket is added for the vent hole, then the venting function is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the waterproof gasket for the liquid through hole and the waterproof gasket for the vent hole into a single integrated waterproof gasket component. This merged structure performs both sealing functions simultaneously, eliminating the need for separate gaskets and reducing overall device complexity while maintaining both liquid sealing and venting capabilities.
Solution Approach 2:
The single waterproof gasket is designed to serve multiple functions: it seals the liquid through hole to prevent leakage and simultaneously seals the vent hole to control venting. This multi-functional design allows one component to replace what would traditionally require separate specialized components, reducing assembly steps and manufacturing cost.
2Adaptability or versatility
If a small waterproof gasket is used for the vent hole, then the venting control is improved, but the reliability decreases due to choking risk
Solution Approach 1:
By merging the vent hole sealing function into the main waterproof gasket, the patent eliminates the separate small gasket that posed a choking hazard. The integrated design ensures that the same robust sealing component used for the liquid path is also used for the vent path, eliminating the risk of small detached parts while maintaining venting control.
3Manufacturing precision
If multiple separate waterproof gaskets are used, then the sealing precision is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent integrates multiple sealing functions into a single waterproof gasket component that can be manufactured as one piece using injection molding. This approach maintains sealing precision by providing dedicated sealing surfaces for both the liquid through hole and vent hole within the same component, while dramatically simplifying manufacturing and assembly by eliminating the need to install multiple separate gaskets.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces manufacturing costs, improves assembly efficiency, and prevents choking hazards by integrating the vent functionality into the waterproof gasket, ensuring reliable operation and safety.
Implementation Method 1
The hemispherical surface is tightly pressed against the liquid through hole of the waterproof gasket
Implementation Method 2
The pivot valve is pivotally connected to and mounted in the chamber of the valve seat and including a hemispherical pivot part

AI summary
A beverage container cap is revealed. The beverage container cap includes a cap body movably disposed on top of a beverage container, a waterproof gasket fixed on bottom of a valve seat with a chamber, and a pivot valve mounted in the chamber of the valve seat. A liquid through hole and at least one vent are arranged at the waterproof gasket. When a hemispherical pivot part of the pivot valve is pivotally rotated within the chamber of the valve seat to make the beverage container cap in a closed or open state, at least one lug on the hemispherical pivot part is pressed against or away from the vent of the waterproof gasket. Thereby pressure in the beverage container is equal to the pressure of the atmosphere outside while beverage in the container flows out. Thus users can drink the beverage from the container smoothly.
